Upgrade your ILCA/Laser by using the latest free running blocks fitted to a genuine class legal ILCA branded block plate. Choose from either our new 29mm Harken Carbo Blocks bolted version, the shackle on Ronstan 30mm version, or our soft-attach versions using 29mm Harken T2 Soft Attach or Allen 30mm blocks. The bolted/shackled versions enables the blocks to be moved from boat to boat. The soft-attach versions are securely fixed with D12 Dyneema. Note that if you are using a compass ‘spider’ attachment that sits over the deck blocks threading the 29mm block versions through is possible – have a look at our videowhich covers this as well as how to attach the bolted on version.
